Hello everyone i am brand new to this site and am seeking help with this newer laptop. It's a Sony Vaio model number (VGN-NR180E) i purchased it 7 months ago for college. It has a Centrino duo processor, with windows vista. When i first purchased it the internet ran great. I have mozzila Firefox and Explorer on this laptop. The problem is i cannot load any web pages on it except face book and Google. I get an error message saying the page cannot be displayed. I am running a quest broadband modem, along wit a net gear router. I also cannot run any updates in my Vaio center or Ad-Aware online updates. This is truly frustrating and any help would be great.
Thanks,
Tyler

firstly, welcome to techspot

I don't think this is mobile computing problem. you may try to post this again in the windows os board. I assume your problem is firewall related but there are alot of other potential causes.
just to mention some:

hosts entries
anti virus software
virus or malware infection
faulty settings in network config
